  • Patent number: 6727437
    Abstract: Methods, memory devices, module boards and systems are disclosed utilizing a non-continuous conductive layer in their circuit board as opposed to a substrate having a continuous length of metal such as copper from one end to the other. By ensuring that a non-continuous conductive layer is no longer present in a substrate, deformation and warping of the substrate or circuit board can be reduced. This can reduce or prevent future errors in processing from occurring due to the tight tolerance required in processing of circuit boards.

  • Patent number: 6634233
    Abstract: A method for the determining ultrasonic sound propagation speed and wall thickness of a tubular object. Time-domain and frequency-domain analyses are used, where the latter can determine acoustic dispersion if the specimen is made up of a dispersive material. Time of flight data is sensed from a series of transmitted ultrasonic waves, some of which are reflected and some of which are transmitted. The time of flight data can be used to calculate speed of sound in the tube, as well as wall thickness. Inherent in the time of flight data is the speed of the ultrasonic wave; accordingly, correction for temperature variations in the tube is not required. The calculations based on measured speed of sound quantities produces more accurate results than in calculations where the speed of sound in the specimen is assumed.

  • Patent number: 6633180
    Abstract: A semiconductor die is provided with an internally programmable router to assign signal paths to select connection points. A switching matrix incorporating at least one antifuse is utilized to selectively route signal paths on the semiconductor die. The chips can then be used individually, for example to reconfigure chip pin assignments to operate in a plurality of different socket layouts, or where features or controls of a chip are selectively enabled or disabled. A further alternative involves programming a first chip, then stacking piggyback, or one on top of the other, the first chip onto a second chip. The contact pins are electrically coupled together, thus avoiding the need for external frames and pin rerouting schemes to form stacked chips. In the stacked chip configuration, control pins are rerouted to align with unused pins on the chip stacked against.

  • Patent number: 6630015
    Abstract: A method and apparatus are provided for separating carbon fibers from gaseous effluent which fibers have been formed in a continuous gas phase reaction. The apparatus is a collection chamber including top and bottom portions and including exit tubes attached to the bottom portion. Carbon fibers enter the top portion of the chamber from a reactor and are collected in the bottom portion where they are forced into the exit tubes by a piston and then collected in bundles. As the fibers are compressed into the tubes, they form an airtight seal which prevents air from entering the chamber and prevents gas from exiting the chamber. The remaining gaseous effluent may then be removed from the chamber and processed for reuse.
